The utility model discloses a conduit saddle body integrated into one piece, processing is convenient, and middle semicircle annular PIR supports section hardness and is higher, utilizes outside ferrule to fix, and stability is higher, is equipped with a plurality of on the elastomer linkage segment at both ends and connects the ladder groove, connects the ladder groove and the butt joint of elastomer insulation material, forms two and connects the face, is difficult to like this to take place to leak, and cold insulation effect is better.
Description
Technical Field
The utility model relates to a technical field of LNG pipeline fixed pipe carrier especially relates to a reduce LNG pipeline cold insulation pipe carrier of link probability of leaking cold.
Background
When using pipelines for transporting LNG, the external environment has a very large influence on the temperature of the liquid in the pipeline. The external environment mainly transfers heat to the liquid in the pipeline through direct heat conduction, heat radiation and the like. Therefore, the pipeline needs to be protected by cold insulation and heat insulation, and the current measures are generally carried out by wrapping an elastomer heat insulation material outside the pipeline. Every interval needs specific conduit saddle to carry out the fixed stay on the pipeline, present general conduit saddle is mostly simple semicircle annular elastomer structure, one then support intensity not very high, when two then semicircle annular elastic structure and elastomer insulation material are connected with sealing glue, only the face of unilateral is connected, the construction is inconvenient, leak cold easily, in case take place expend with heat and contract with cold and leak easily, leak department can freeze this moment, the temperature can extremely fast conduct, influence whole pipe-line transportation.
Disclosure of Invention
The utility model discloses aim at solving prior art's not enough, and provide a LNG pipeline cold insulation conduit saddle that reduces link and leak cold probability.
The utility model discloses a realize above-mentioned purpose, adopt following technical scheme:
the utility model provides a reduce LNG pipeline cold insulation conduit saddle of link probability of leaking cold, includes the conduit saddle body of embracing two symmetries of fixing on the LNG pipeline, adopts sealed glue to connect between two conduit saddle bodies, and every conduit saddle body all includes the semicircular ring shape PIR support section in the middle of and is located the elastomer linkage segment at semicircular ring shape PIR support section both ends, semicircular ring shape PIR support section, elastomer linkage segment are the integrative shaping of pouring, be equipped with a plurality of connection ladder groove from semicircular ring shape PIR support section to the direction of tip on the elastomer linkage segment outer wall.
And a moisture-proof layer is arranged on the outer wall of the semicircular PIR supporting section.
The dampproof course is three proofings cloth dampproof course or fire prevention cloth dampproof course.
The connecting stepped grooves at each end are four in number, the length of each connecting stepped groove is 50mm, and the thickness of each connecting stepped groove is 25 mm.
The elastomer connecting section is a composite structure of alkadiene and nitrile rubber.
The utility model has the advantages that: the utility model discloses a conduit saddle body integrated into one piece, processing is convenient, and middle semicircle annular PIR supports section hardness and is higher, utilizes outside ferrule to fix, and stability is higher, is equipped with a plurality of on the elastomer linkage segment at both ends and connects the ladder groove, utilizes the different connection ladder groove and elastomer insulation material butt joint one by one, forms two connection faces this moment, is difficult to take place to leak like this, and the cold insulation effect is better.
